Question about Cars & Trucks
Check engine light is on, dealer says fuel filler neck needs to be replaced. Could it be that all I have to do is replace the gas cap?

The EVAP system on OBD-II equipped vehicles is monitored by the computer. When the gas cap is bad, or if there is a break in the system somewhere, this alerts the computer (ECU) of a problem and the ECU will turn on the check engine light to alert you of a problem. Although not normal, it is something that can happen and need replacement. You can inspect the filler neck yourself for visible damage (it is the flexible/ribbed hose going into your fuel tank from the filler) and replace the gas cap yourself. i might suggest replacing the gas cap and then having an Auto Zone or Napa reset your computer to see if the cap was the extent of the problem before i paid a shop to replace the filler neck. If the cap was specified as a problem, you really have nothing to lose on pursuing this fix first. Also, if you can order the filler neck, this is a relatively easy replacement and requires only shadetree mechanic skills.
i hope this helps,
